EDEN: Novel power-to-power system for enhanced hydrogen storage in solid state

EDEN aims at research, development and validation of a solid-state hydrogen storage technology for specific sector of stationary applications and at support of distributed grid level applications. EDEN realizes a full-scale prototype composed by a storage tank, R-SOC (reversible-Solid Oxide Cell) and an energy recovery solution, which allows overall efficiency improvement and that, is compatible for the use with "polluted" hydrogen. The main objectives of this research project address the development of a new storage material with high hydrogen storage capacity, loaded into a specifically designed storage tank and fully integrated with R-SOC. 10 kg material has been prepared. The intermediate tests demonstrated 7.1 w/w % hydrogen density on the material. Once completed the development and lab characterization, EDEN system prototype has been installed in FBK in Trento, in order to evaluate system performances in real working condition. The demonstration of the technology will be completed in Barcelona, in a selected site controlled by the Barcelona Energy Agency.
